trouble sending post request with to laravel end point for razorpay order ceration

when i send a get request here every thing works perfectly fine but post request gives me errors
react method for sending to payment.razorpay route

`const handlePayment = ()=>{
localStorage.setItem(‘selectedSeats’, selectedSeats);

axios.post(route('seats.checkAvailability'), { selectedSeats })
.then(response => {
  console.log('Success:', response.data);
  try{
      axios.post(route('payment.razorpay'), {
        selectedSeats,
        totalAmount: total,
        user: auth.user
      },
      {headers:{"Content-Type" : "application/json"}}
    );
  } catch (error) {
    console.error(error.response.data);
  }
})
.catch(error => {
  console.log('in catch');
  setErr(error.response.data.error);
});

};`

here is the route
Route::post('/razorpay', [PaymentController::class, 'processPayment'])->middleware(['auth'])->name('payment.razorpay');

function in PaymentController
` public function processPayment( Request $request)
{

    dd('here');

    $request->validate([
        'selectedSeats' => 'required|array',
        'total' => 'required|numeric|min:0',
        '$user' => 'required'
    ]);

    $selectedSeats = $request->input('selectedSeats');
    $totalAmount = $request->input('total'); 
    $user = $request->user();

    $api_key = config('services.razorpay.razorpay_key');
    $api_secret = config('services.razorpay.razorpay_secret');
    $api = new Api($api_key, $api_secret);
    
    try {
    $order = $api->order->create([
        'amount' => $totalAmount * 100,
        'currency' => 'INR',
        'receipt' => 'order_receipt_id_123',
        'payment_capture' => 1 // Auto capture payment
    ]);
    } catch (Exception $e) {
        return response()->json(['status' => 'error', 'message' => 'Failed to create Razorpay order'], 500);
    }

    $data = [
        "key"  => $api_key, 
        "amount" => $order['amount'], // In paise
        "currency" => $order['currency'],
        "name" => $user->name,
        "description" => "Ticket Purchase",
        "image" => "https://cdn.razorpay.com/logos/GhRQcyean79PqE_medium.png",
        "prefill" => [
            "name" => $user->name,
            "email" => $user->email
        ],
        "theme" => [
            "color"  => "#3399cc"
        ],
        "order_id" => $order['id'], // Pass the order ID from Razorpay
    ];

    return Inertia::render('Checkout', [
        'data' => $data, // No need to json_encode here, Inertia will handle it
        'selectedSeats' => $selectedSeats, // Pass selected seats to the view
        'totalAmount' => $totalAmount, // Pass the total amount
    ]);
}`

i tried adding a dd() at the start of the function but the request wont even reach there
i also tried using Inertia.post

should i keep this as a get route cause it works perfectly fine, if yes where should i pass the data ?
